Which ventilation systems are designed to recover and reuse energy from exhaust air?

Energy Recovery Ventilation Systems are specifically designed to improve the efficiency of ventilation by recovering and reusing energy from exhaust air. These systems work by transferring heat and moisture between incoming and outgoing air streams. During the winter, for instance, warm air leaving the building can preheat the cooler incoming air, reducing the energy burden on heating systems. Conversely, during the summer, these systems can cool the incoming air using the cooler exhaust.

Unlike natural ventilation systems, which rely on passive airflow and do not actively manage energy reuse, or heat exhaust systems, which focus on removing hot air rather than recovering energy, and active ventilation systems, which may involve mechanical means to move air but do not necessarily include energy recovery features, Energy Recovery Ventilation Systems stand out by incorporating this energy recovery function. This allows buildings to maintain better indoor air quality while minimizing energy use, making them a key component in energy-efficient building design.
